Why build one when you can build two at twice the price!

Seriously though, the cost was largely in the preparation. At some point you want to get more out of all that work. Yes, it was expensive for each actual launch. I wonder what the cost of stopping at the first one would have been. I’m WAGing that half the cost was getting there the first time. The other half was 5 more. That would be an interesting stat to know.
